Capnocytophaga canis strain 17-158 61

Capnocytophaga canis strain 17-158 61 is a Gram-negative, microaerophilic bacterium notable for its pathogenic potential in humans and animals. It possesses true flagella, which facilitate motility and may contribute to its virulence. This strain has a single replicon, indicating a streamlined genetic architecture that can impact its adaptability and growth. C. canis is primarily associated with three hosts: Homo sapiens (humans), Canis lupus familiaris (domestic dogs), and Felis catus (domestic cats). It is important to note that while the bacterium can cause mild local infections in humans, it is more notably linked to sepsis, particularly in immunocompromised individuals. This highlights the potential health risks associated with close contact between humans and pets, especially dogs, which are common reservoirs of the organism. The strain's microaerophilic nature suggests that it thrives in environments with lower levels of oxygen, which may influence its habitat and interactions with the host's microbiota. Understanding the ecological niche of C. canis can provide insights into its transmission dynamics and pathogenicity. In summary, Capnocytophaga canis strain 17-158 61 exemplifies the complexities of host-pathogen interactions and underscores the importance of pet ownership in public health contexts, particularly concerning zoonotic infections. Its distinct traits, including its Gram-negative status, microaerophilic requirements, and pathogenic effects, contribute to its role in both veterinary and human medicine.
